I just saw the very curious title:
An Operator-Like Description of Love Affairs
by: Fabio Bagarello and Francesco Oliveri SIAM J. Appl. Math. Volume 70, Issue 8, pp. 3235-3251 (2010)
And with the report of this title, I also admit that this title belongs to the category of memorable titles, without first needing to read the paper. The abstract of the paper is also quite curious!
